TechBrief: Curing Concrete Paving Mixtures
Primary Topic: Materials-Concrete
Description: This Tech Brief focuses specifically on approaches commonly used for curing cast-in-place concrete pavements. The most common method is the application of membrane-forming curing compounds, although fogging, plastic sheets, wetted materials, and insulated blankets may also be used depending on the type of project and the ambient conditions during and after placement. Also discussed briefly is internal curing using prewetted lightweight aggregate (ACI 2013; Weiss 2016). In the context of this Tech Brief, two curing steps are considered: 1) initial curing applied during or immediately after the concrete is placed under less-than-favorable conditions, and 2) conventional curing applied once the concrete has undergone initial set.
